Frequency of different cases of orthologous relationships for a given gene in a syntenic region between human and mouse.

<p>Italic font indicates classes of genes that are covered by SyntenyMapper. Internal orthologs: Orthologous genes that lie in the same syntenic region. External orthologs: Orthologous genes that lie in different syntenic regions. Syntenic-block-free region: Genomic region that is not covered by ENSEMBL syntenic regions.</p><p>Frequency of different cases of orthologous relationships for a given gene in a syntenic region between human and mouse.
